vSphere Host Profiles can be used to maintain a standard configuration across clusters of ESXi hosts. However, every host will have a set of unique settings—for instance, the IP addresses of the VMkernel interfaces. You can modify such unique settings by launching the Edit Host Customizations wizard for each object (cluster/host). However, it is understandably an error-prone and cumbersome process to edit the setting of each host using the wizard interface.
An alternative and efficient method would be to prepare a customizations (.csv) file with the host-specific values and use it to perform the host customization.
In this recipe, we will learn how to export and prepare a customization file and then use it for remediating customizations to the attached objects.
The following diagram depicts a high-level overview of this process:
